What does it mean that he was staring at me?

There's this guy in one of my classes and we had to work together for this peer editing thing. While I was telling him what he could fix and change I would be looking back and forth between his paper and him. Every time I would look up at him he was staring directly at me. what does that mean?

(P.S he also sits across from me so we always make some kind of eye contact)

Obviously I want it to mean something. I know there wasn't anything on my face because he was staring right in my eyes.and it wasn't like he was trying not to laugh or anything he had a serious look on his face.
